Detailed Bypass Surgical Procedure (Whole Vena-cava Anastomosis)







It consists in al

anastomosis between

the portal vein

and the interior vena-cava.



When the portal blood is devivated from the vena-cava

the pressure over the portal system is diminished

and danger of hemorrhage from esophagus

and gastric varicosity is reduced.



When the vena-cava can not be

used because of an obstruction

by thrombosis or any other reason

one proceeds by a spleen-renal



deviation

between the spleen

vena and

the renal left vena.
